H&P, tests. Through nuclear stress test, stress echocardiogram, echocardiogram, pet scan, ct scan, and ekgs. These tests are only used after a thorough history and physical that provides the indications for the appropriate test (s).
Heart diagnosis. To diagnose heart disease we use history, physical exam, ecg, chest xray, echocardiogram, various imaging and nuclear imaging studies and cardiac catheterization and coronary angiography. There are other tests also which I haven't mentioned.
Depends on the type. Of heart disorder. Young people often have congenital lesions that do not affect blood tests. Older people have mostly atherosclerotic heart disease, and common test for that are fasting blood lipids, c-reactive protein, bnp and troponin. It would be prudent to consult your doctor for proper choice of tests based on your clinical history and physical findings.
ECG. ECG is a basic test in cardiac diagnosis. If your cardiac problem is arrhythmia, the ECG is crucial/essential. Because of the complex nature of heart disease, we want an ECG on everybody as part of their cardiac evaluation.
Primary yardstick. This is the starting place. There are more definitive metrics such as echo-cardiogram;however let's do the basics first.
Ecg. The ECG is diagnostic for cardiac rhythm, it is indicative of other things. After history and physical exam it is one of the first basic tests we use. Other tests are more informative for things other than rhythm.
It can't. It can give us valuable clues but if it did everything there would be no other tests.
H&P. History and physical exam (h&p) which includes an ECG (electrocardiogram) and possibly a chest x-ray.
Many things. The first and most important thing in making a diagnosis is listening to the patient. Their signs and symptoms are important. The next is a physical exam. Tests which help include ekg, stress tests, angiogram which visualizes the blockages. Newer tests include ct angiograms, ct calcium score, and mri' s are beginning help as well.
